Chapter 20: The Abyss Awakens

As Chen Heo Jeong lay defeated, his once formidable powers waning, a sense of foreboding settled over the warehouse. Suddenly, with a desperate cry, Chen unleashed his last resort – opening a gateway to the realm of demons.

A rift tore through the fabric of reality, unleashing a horde of otherworldly creatures into the world. The air crackled with dark energy as the demons poured forth, their twisted forms casting shadows that seemed to devour all light.

"We have to stop them!" Taehyun shouted, his voice filled with urgency.

Joon-ho gritted his teeth, his sword at the ready. "We can't let them overrun Seoul!"

Soo-jin's bow hummed with power as she took aim. "We'll fight them back, no matter what."

With a shared nod, they charged into battle once more, their weapons flashing in the darkness as they clashed with the demonic horde. But the creatures were relentless, their numbers seemingly endless as they swarmed over everything in their path.

As the battle raged on, Taehyun, Joon-ho, and Soo-jin fought with all their might, pushing themselves to their limits in a desperate bid to stem the tide of darkness. But for every demon they struck down, two more seemed to take its place.

"We can't keep this up forever!" Joon-ho shouted, his voice strained with exertion.

Taehyun's brow furrowed in determination. "We have to find a way to close the gateway. That's our only chance."

Soo-jin nodded, her eyes scanning the chaos around them. "I'll cover you. Go!"

With a nod of thanks, Taehyun dashed towards the rift, his heart pounding in his chest. He could feel the pull of the demonic energy, threatening to consume him whole.

But with every step, he drew upon the light within him, pushing back against the darkness with all his strength. And as he reached the rift, he summoned every ounce of his power, channeling it into a beam of pure light that surged towards the gateway.

With a deafening roar, the rift began to collapse in on itself, sealing off the realm of demons once more. The creatures howled in agony as they were pulled back into the abyss, their screams fading into the distance.

As the last of the demons vanished from sight, a heavy silence settled over the warehouse. Taehyun staggered back, exhaustion washing over him as he collapsed to his knees.

But amidst the chaos and destruction, there was a glimmer of hope. For in the face of overwhelming darkness, Taehyun, Joon-ho, and Soo-jin had once again emerged victorious.
